The pair of case receiving portions 45 reinforce the insulating case member 22 . In this way, since the insulating case member 22 is reinforced by the pair of case receiving portions 45 of the ground contact member 21, the wall thickness of the insulating case member 22 is reduced without impairing the mechanical strength necessary for the insulating case member 22. Therefore, when the coaxial connector device 10 is mated and connected with the counterpart coaxial connector device 30 mounted on the circuit board, it can be achieved that the mounting surface of parts and the like of the circuit board on which the counterpart coaxial connector device 30 is mounted protrudes. The dimension in the direction perpendicular to the mounting surface of the components of the circuit board, that is, the thickness dimension of the coaxial connector device 10 is reduced.

As a result, a state in which the central conductor 12 of the coaxial cable 11 is connected to the central conductor connection portion 52 of the contact member 20 is obtained. In this case, there is no need to solder the central conductor 12 of the coaxial cable 11 to the central conductor connection portion 52 of the contact member 20 . In addition, the pressing force generated at this time is applied to the holding portion 41 of the insulating case member 22 and received by the pair of case receiving portions 45 extending from the annular fitting portion 26 of the ground contact member 21, thereby securing sufficient strength. , It is difficult to cause damage such as deformation.

And, on the basis that the central conductor 12 of the coaxial cable 11 is connected with the central conductor connection portion 52 of the contact member 20, in the contact member 20, a pair of contact terminal portions 53 and the central conductor 12 connected with the coaxial cable 11 Both of the central conductor connection portions 52 protrude from the flat connection portion 54 in the same direction. These contribute to a reduction in the thickness dimension of the coaxial connector device 10 .

Next, a pair of first bent and clamped portions 46, a pair of second bent and clamped portions 47, and a pair of third bent and clamped portions provided on the shell portion 44 of the bent ground contact member 21 48 are respectively bent to obtain the following state: a pair of first bending and clamping parts 46 clamp the holding part 41 of the insulating housing member 22, and a pair of second bending and clamping parts 47 clamp the outer side of the coaxial cable 11 The conductor 14 and the pair of third bent holding portions 48 hold the outer skin insulator 15 of the coaxial cable 11 . As a result, the coaxial connector device 10 mounted on one end of the coaxial cable 11 as shown in FIGS. 1 to 3 is obtained.

On the basis that the coaxial connector device 10 is assembled to one end of the coaxial cable 11, a through hole 42 is formed in the holding portion 41 of the insulating housing member 22, and a central conductor connection portion constituting the contact member 20 The fixing part 50 of 52 is formed with a through hole 55, and the through hole 55 is arranged at a position corresponding to the through hole 42, so that the through hole 42 and the through hole 55 can be passed from the bottom surface part side of the holding part 41 of the insulating housing part 22. On the other hand, the central conductor 12 of the coaxial cable 11 connected to the central conductor connection portion 52 of the contact member 20 is visually observed. And, by such visual inspection, it is possible to confirm the state of connection between the central conductor 12 of the coaxial cable 11 and the central conductor connection portion 52 of the contact member 20 .

In the coaxial connector device 10 as described above, when fitted to one end of the coaxial cable 11, the fixed portion 50 and the movable portion 51 of the central conductor connecting portion 52 of the contact member 20 and the fixed portion 50 and the movable portion 51 The central conductor 12 of the coaxial cable 11 clamped by the movable part 51 is not arranged in the ring-shaped fitting part of the ground contact member 21 when the coaxial connector device 10 is fitted and connected to the counterpart coaxial connector device 30 . The inner side of the portion 26 overlaps with the center contact 35 of the counterpart coaxial connector device 30 to which a pair of contact terminal portions 53 of the contact member 20 are contacted. In addition, the contact member 20 is connected to the coaxial cable 11 The central conductor connecting portion 52 of the central conductor 12 protrudes from the flat connecting portion 54 in the same direction as the pair of contact terminal portions 53, so that the mounting surface of parts and the like of the circuit board on which the counterpart coaxial connector device 30 is mounted can be achieved. The protruding direction, that is, the dimension in the direction perpendicular to the mounting surface of components and the like of the circuit board, that is, the reduction in the thickness dimension.

Furthermore, on this basis, the bent contact portion 40 provided on the insulating case member 22 is bent along with the shell portion 44 of the ground contact member 21 , and the center conductor is pressed by the bent contact portion 40 .
